2133.04
Revocation of declaration.

(A)
A
declarant may revoke a declaration at any time and in any manner. The
revocation shall be effective when the declarant expresses an intention to
revoke the declaration, except that, if the declarant made the declarant's
attending physician aware of the declaration, the revocation shall be effective
upon its communication to the attending physician of the declarant by the
declarant, a witness to the revocation, or other health care personnel to whom
the revocation is communicated by that witness. Absent actual knowledge to the
contrary, the attending physician of a declarant and other health care
personnel who are informed of the revocation of a declaration by an alleged
witness may rely on the information and act in accordance with the
revocation.

(B)
Upon the
communication as described in division (A) of this section to the attending
physician of a declarant of the fact that the declaration has been revoked, the
attending physician or other health care personnel acting under the direction
of the attending physician shall make the fact a part of the declarant's
medical record.

(C)
Unless a declaration provides otherwise, a declaration
is revoked by a subsequent declaration.
